the drop in hp at low rpm's is do to two factors- #1 when going through the gears on a dyno depending on how high you bring the rpms up in 3rd going to 4th ( being the test gear ) you will have a difference in variables of the time vs rpm's & WOD ( wide open throttle ) that can play havic on the low rpm #'s. but its not to say it didn't lows power down low.
#2 when going to any aftermarket intake,which essentially frees up the intake track,it
will resault in a small hp loss at low rpm's. its the nature of the beast.
with a rotory motor you strive to make power up high.you basically have no choose,
that goes for any small displacement motor.
on the dyno you could hear the rpm's climb faster with the jet stream filter,the faster your rpm's climb the more power your making,the motor really liked it.the power is very smooth on the top end, you can see that on the dyno graph, thats those 10 hp
spots i was talking about.

as far as testing our kit against other kits, its not in our practise, we design the best possible kit with our unique patented filters, going into this dyno session i was aware
that there was only about 2whp too make-we made 3!! but thats peak power, you have to look at the graph carefully, there's more then 3 whp there.

i'll have the rpm's graph for you soon,i'll try & get some targeted rpm hp figures to show you what i mean.

i have only 5 kits coming in at a group buy price of $220.00 each.

let me know if your interested.

What kind of dyno? 168hp stock is definitely on the low end...

 

I agree that, at lower RPM (street driving), the MSCAI makes the car less powerful below 4000 rpm

 

jetstreamer I am still down. an ecu tune will make good use of an intake and free flowing exhaust.

 

the test was performed on a dyno jet, the car had winter tires on it,
not sure if they're larger or heavier then the reg. tires, if they are the # will be lower.

I'm curious/interested. Been thinking about swapping out my MS CAI for K&N intake, but maybe this one will do the job. hhhmmmm I will have to wait for it to warm up tho, cause I ain't taking the front bumper off in this weather...bbuurrr

 

So you guys tell me...here's a comparison

AEM/MS intake dyno

To me it seems best overall is K&N?? But I'm not the best at reading these dyno charts.

 

don't believe everything you see, look at the smoothing on the top right, K&N has it on 5,
it should only be at 1 like our graph. there has been independant testing to comfirm that on a stock RX-8 there is only 2 to 4 peak whp to gain.
Our test was straight up with the customer & many witnesses there, this was not a closed dyno session.all the operater has to do is let off on the gas pedal on the very
top end & you'll see exactly what you see on the that chart.its that simple!smoothing on 5 = ????



Our Graph is 100% true. no screwing around here!!!

I never do hence why I always question and research research research!!

I know jack about dyno's and not afraid to admit it. I know they don't produce 11whp no CAI does. Lucky to get any gains by what I have read. Was just wondering overall best one to get that's all!

Cheers!

 

I think you should just keep what you have, and spend the $300 elsewhere. Some very useful items to have for the 8 are things like a Scangauge...

 

Footman...I luv the MS CAI, but can't stand the worry factor of car washes etc. I can sell it for what a new or slightly used one will cost me.

 

Hi Gerry,

Just a quick question.. in looking at the pics you posted earlier.. your intake doesn't actually loop through the front bumper correct?

I've got a RB Ram Air duct on it's way (which just forces air up from the front bumper to where the stockbox starts).. so.. if I can use yours with that... chances are I'll pick one up from you in the spring..

 

the intake ends & draws air from the stock inlet location in the engine bay,it doesn't go into the bumper.no need to!!!the air coming through the inlet is ambiant. all our systems are safe to run in the rain.

the ram air duct will work great as long as it doesn't direct water into the filter.

race teams use our filters with ram air setups all the time. nothing better then that !!

daily street driving is another ball game, motors don't like water , as long as its only directed air towards the inlet you should be fine.

gerry

 

This is sounding like a promising set up. RB Ram and the jetstream. Good idea REV.

 

Thumper, don't worry about MS CAI and rain.. I have plenty of experience with it.... you just have to follow the guidelines I present in the threads for car washes...

if I can run it, and QTWRE can run it (with the MS BUMPER) all year round, so can you

 

I'm not to worry about rain, has never been an issue, car washes tho...different story.

 

I'm not convinced this is a cold air intake as while it may be sitting in front of that hole where the stock intake protrudes, the wind isn't exactly going to be blowing through there, which will give the filter plenty of opportunity to suck in the hotter ambient air. Even some sort of rubber extension on the end would be nice just to actually get the inlet outside the engine bay.

Is this a $299 air filter? I've looked around the website and it basically looks like a few filters have been designed of different lengths and they're used as space allows in various engine bays. Some of the other applications of this filter seem a fair bit more complex in design for a lesser price.

Is it possible to see that upcoming dyno chart with an AFR graph so we know it isn't just a matter of turbulence leaning out the MAF?

Sorry for the skepticism. I hope to be shown I'm wrong.

 

Yes, it is a cold air intake. It is taking cold out side air, rather than heated engine air.
I think what you are looking for is a ram air intake. This could be made into that with the Racing Beat duct.

 

if it is a cold air intake, then shouldn't it be getting air from in front of the bumper steel piece (like the MS CAI) as opposed to getting the air from the engine compartment where the stock intake air box is?

I think I'm repeating myself, but somewhere in this thread in the beginning, I have asked that question...

 

Like I said Thumper, if I can survive the car washes.. so can you

 

I respectfully disagree. Its inlet is still within the engine bay. I'm sure it is getting some fresh air but it's also bound to get a good helping of the engine bay air as there's no sort of ducting to direct its intake to that fresh outside air. The stock intake isn't ram air but it is cold air.

This is just speculation of course. A good test would be to actually gauge it with a CAN reader before and after. Maybe not worth the work to get the test car back in the shop though. Just an idea to help the marketing.
